AI Summary: Add a `--hydration-tasks` argument to the `export` command of the `smart-fetch` tool, allowing users to specify which hydration tasks to run during export. This includes adding a `none` option to disable hydration entirely. The argument should accept a comma-separated list of tasks, mirroring the functionality of the existing `hydrate` command.

AI Summary: Modify the `smart-fetch` command-line tool to accept the `--type` argument multiple times, either as repeated flags or as a comma-separated list, mirroring the existing functionality of `--type-filter`. This involves adapting existing code from Cumulus ETL to handle multiple occurrences of the `--type` argument.
